Cytoskeleton Quiz

What is the primary function of microtubules in the cell?

• To form the cell cortex

• To assist in cell signaling

• To give the cell its shape and support

• To provide flexibility to the cell

Which type of protein assembles into actin filaments?

• Keratin

• Tubulin

• Collagen

• Actin

What is the role of actin filaments in cell movement?

• They relay signals

• They rearrange to form pseudopods

• They form hollow tubes for transport

• They anchor organelles

What is a unique feature of intermediate filaments compared to other cytoskeletal components?

• They form the cell cortex

• They are involved in cell signaling

• They are made of a variety of proteins

• They are the longest filaments

How does the cytoskeleton contribute to cell division?

• By relaying signals to other parts of the cell

• By forming pseudopods

• By anchoring cells to the extracellular matrix

• By separating chromosomes and building new cell walls
